Located at the top of cobblestone Hidalgo Street, the church recently underwent a thorough renovation, inside and out. The south-facing main and east-facing side façades, both originals and both well preserved, have elaborate geometric patterns carved into their surfaces — their design unique in the city. Inside, little remains of the original furnishings and ornamentation, the interior long ago stripped of its colonial character. That said, in the choir loft, above the main portal, there’s a beautiful, old post-colonial pipe organ, which was built in 1866 and has now been completely restored.
